2000 mazda b2500 2.5l flutters &stalls after reving engine has tdc p1401 what is the problem

The dfpe is essentially a flow meter that measures the flow of exhaust gasses returning to the intake manifold when the pcm opens the egr valve. This code is telling you it is not getting data from sensor. Could be the sensor has failed, has been disconnected, or the wiring/connector is bad. Since the engine is stalling, it may be that the egr valve is stuck open or the pipe between the exhaust manifold and the intake manifold has come loose. Inspect the egr pipe, valve, and sensor connections.
The figure below is for the 3 l engine. I could not find the 2.5. See the two ports near the top of the tube? Those will vave vacuum lines attached that lead to the dfpe sensor.

Why is my engine light still on p1071

i believe this is a burning lean code meaning that your engine is using more air than gas and the o2 sensors don't my advice is to find the **** which usually is the mass air flow meter it gets dirty on one side and tells the computer that it is getting little air and computer compensates to burn even ratio fuel to air but reality is air is plentiful .so best to remove the mass air flow meter spray the sensor tips with carb clean and using a lite brush clean it well reset the light by unplugging the battery and drive it. also check for exhaust leaks in between the o2 sensors.hope this helps you.

Catalyst system efficiency below threshhold bank 2

before replacing cat converter replace o2 sensors, they go bad and give a false reading that cat efficiency is below threshold ,meaning converter is no good , i would replace o2 sensors and reset engine light and go from there,the o2 s are normaly the problem, unless you hear cat rattling, well good luck,

I can't give my jeep much gas or it will backfire and die. i have changed the tps and the mass air flow sensor and the fuel pump, 2000 grand cherokee.

Have your fuel pressure checked. It may be a bad regulator.

Try cleaning the throttlebody and air filter.

Check your spark plugs, coil and wires.

Check and make sure all of your injectors are clean.

Also you may want to check your o2 sensors. You can unplug them and drive a bit. If the problem goes away then they need replaced.

I would replace the O2 sensor on general principles and have a look at the screen sensor for the air flow sensing unit just ahead and slightly right of the coolant tank and behind and in line of the air filter housing. That little screen and its readings along with the O2 sensor and various other sensors can really mess up the idle and fuel consumption. The little sensor screen can be washed and cleaned of **** with alcohol and it will work as new. the O2 sensor needs a lot more persuasion
